摘要
利用化学分析方法,探讨了沥青在热、光、氧、臭氧等自然因素作用下可能发生的老化化学反应,指出在通常的自然条件下,沥青中各组分会自行发生热氧化老化、光氧老化、臭氧老化等老化反应,分析提出了这一过程中的化学反应方程式,从化学反应角度揭示了沥青老化的化学机理.
By using chemical analytic methods, the authors in this article discuss the aging chemical reactions of asphalt that can occur under effects of natural factors such as heat, ray, oxygen and ozone. It is pointed that the heat-oxidizing aging reaction, ray-oxidizing aging reaction and ozone aging reaction would take place in the components of asphalt under normal natural environment. The authors also put forward several chemical reaction equations in the process and tried to reveal the chemical aging mechanism of asphalt.
